Toothing is a technological evolution of the sexual practice known as "dogging". People with Bluetooth enabled mobile devices broadcast to other Bluetooth enabled devices in the area that they are "up for a shag" They text some flirtatious sexual banter back and forth for a bit, then arrange to meet up for an impromptu shag in the nearest nook or cranny.

Im not going to the pub tonight, im feeling a bit horny, gonna go toothing at Liverpool Street Station instead.

A new communication instrument that using in a creative way the bluetooth technology creates a new form of mobile urban social interaction.
A new way to reduce the 6 degrees of separation everyone has, and to create urban network an mobile community.
